Turquoise-Style Oval Bead Necklace with Silver-Tone Extender

This is a single-strand fashion necklace featuring approximately 24 large, oval-shaped polished beads. The beads exhibit a vibrant cyan-blue color with a dark grey or black spiderweb matrix, characteristic of turquoise or simulated turquoise materials like dyed howlite or magnesite. Each bead measures roughly 2 to 3 centimeters in length, with a flattened oval cross-section. The construction consists of beads strung on a flexible cord with small, dark separator beads occasionally visible between the large focal stones. The closure features a silver-tone metal lobster claw clasp and a matching curb-link extender chain, which allows for adjustable length and terminates in a small metal decorative bead. The hardware shows slight signs of surface wear and oxidation consistent with contemporary costume jewelry. The overall condition appears excellent with no visible cracks or chips in the beads. Given the uniform color and consistent 'webbing' patterns, this item is likely a modern fashion piece (21st century) designed to emulate Southwestern or bohemian styles. The lack of visible hallmarks on the clasp suggests it is a mass-produced accessory rather than a high-end designer or fine jewelry item.
